stereoselectivity are discussed. Reaction of the oxaziridines with iron(II) sulfate, tributyltin hydride, or copper(I)triphenylphosphine chloride tetramer gave products arising from deoxygenation in many cases; however the trans-isomers also gave products derived from cyclisation of the intermediate aminyl radicals onto the pendant alkenyl chains.
